Avalanche Problems

Loose Wet

Expect loose releases around trees and rocks to pull the top 20-40cm of snow later in the day as temperatures warm and solar radiation weakens the surface layers

Aspects: North, North East, East, South East, South.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 3

Storm Slabs

60 to 70 cm of recent storm snow has settled into a cohesive slab above a late March crust. Failures within the slab have been observed recently. Sudden planar results are still being observed on the crust.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 3

Deep Persistent Slabs

The Feb 8 surface hoar is still worth keeping in mind. No recent failures have been observed on this layer. Cornice fall or glide crack failure are the most likely triggers.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 4
